Unable to boot into windows after removing Ubuntu 20.04

Question

after realizing I installed the wrong Ubuntu version(20.04), I wanted to remove it and then install the correct version(18.04).

I used this guide:

However, steps 6 and 8 do not work for me. Therefore, I tried solutions from here:

However, insmod chain throws the "Error" unsupported filesystem.

And, the approach using diskpart (from a repair usb stick) doesn't work, as step 9 (Z: dir) returns "File not found".

Could someone help me fix my Windows partition?

Does this answer your question? How to remove Ubuntu and put Windows back on? — karel, May 08 '20 at 14:42
It sounds like the "fix MBR" command failed in the instructions you followed. — , May 08 '20 at 14:43
Step 6 from the guide worked for me! I am just saying that for other people who might consider following this guide. — bing-nagata-smirnov, Feb 26 '21 at 21:13

connect to the Internet
open a new Terminal, then type the following commands (press Enter after each line):

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update

And follow Recommended repair for more detail.

Is Windows UEFI or BIOS install? Just be sure to boot Ubuntu live installer in same boot mode and use ppa to add Boot-Repair. If still issues post link to summary report. – oldfred May 08 '20 at 14:49
